GASOLINE VAPORI ZER Filed Oct. 27, 1930 Patented July 12, 1932 UNITEDstares PATENT OFFICE GASOLINE VAPORIZER Application filed October 27,1930. Serial No. 491,508.

This invention is for a gasoline vaporizer adapted to be interposed inthe intake circuit of an internal combustion engine, and has for itsmain object, the interposition of a device between the carburetor andthe intake manifold adapted to create eddy currents, whereby a morecomplete vaporization of the fuel is obtained.

Another object of the invention is to provide a device as outlined,which, due to the more complete vaporization of the fuel, results infuel economy and increased power of the engine.

Other objects and advantages of the in vention will be apparent as thedescription is read on the drawing forming a part of this specification.

The invention consists substantially of a Venturi tube, having atransverse wall of inverted V form, the wall extending downwardlyadjacent the open butterfly valve of the carburetor, and the tube havinga flange conforming to the carburetor flange.

The invention is adequately illustrated in the accompanying drawing, inwhich:

Fig. 1 is a fragmentary sectional view of the intake manifold andcarburetor, with the invention interposed;

gig. 2 is a top plan View of the invention; an

Fig. 3 is a longitudinal sectional elevation through the inventionindicating the transverse wall.

Similar reference characters are used to designate similar partsthroughout the sevcral views.

The invention consists of a frusto-spherical member 10, adapted to fitwithin the intake manifold 11 of an internal combustion motor, andprovided with a flange 12 adapted to mate with the carburetor flange 13and the intake manifold flange 14, bolt holes 15 being provided toregister with the bolt holes in flanges 13 and 14:. Centrally disposedand extending adjacent the top of the frustospherical member 10 is anintegral transverse wall 16, the top being formed to inverted V shape 17to a point adjacent the bottom of the flange 12, then continuingdownwardly into a straight wall 18 extending below the bottom of flange12 the straight wall having an arcuate relief 19 to clear the butterflyvalve 20 of the carburetor 21, the wall substantially fitting tranversely within the carburetor outlet 22. 5

The operation of the device is as follows: A mixture of air, gasolinevapor and gasoline mist is drawn through the carburetor outlet 22 andthrough the restricted aperture 23 where its velocity is increased, passing into the intake manifold where due to the enlarged area, thevelocity is again decreased, causing eddy currents as indicated by thearrows, and causing thereby a thorough scrubbing action of the air andvapor with the mist, causing the mist to vaporize before being drawninto the combustion chamber. The transverse wall with the upper knifeedge aids in intensifying the eddies, and also collects unvaporizedgasoline on the surface which is immediately exposed to the action ofair and vapors and thereby vaporized.

The thoroughly vaporized and intermixed gas provided by the inventionresults in increased power and gasoline economy.

The device is installed by removing the bolts 24 which secure thecarburetor to the intake manifold, )lacing the invention between theflanges, with the Venturi-tube extending upwardly into the intakemanifold, and replacing the bolts 24. Gaskets 25 are preferably placedbetween both flanges and the invention, as shown.

Having described an operative method of constructing and using thedevice, it will be understood that variations in construction andarrangement, which are consistent with the appended claims, may beresorted to without detracting from the spirit or scope of theinvention, or sacrificing any of the advantages thereof.

I claim:

1. A gaseous fuel mixing device adapted to be inserted between acarburetor and an intake manifold comprising a frusto-spherical Venturitube provided with a flange ex tending outwardly from the base thereof,and a transverse, centrally disposed wall extending from a pointadjacent the top, and

downwardly beyond the base, said wall having a concavity formed at thelower end on a transverse axis.

2. A gaseous fuel mixing device comprising a frusto-spherical Venturitube having a radial flange extending from the base thereof adapted tobe interposed between the flanges of a carburetor and intake manifold,apertures in said flange in registry with the bolt apertures in thecarburetor and intake manifold flanges, a vertical wall centrallydisposed in said Venturi tube extending from adJacent the top thereof toa point below said flange, the upper end of said wall converging to aninverted V shape edge, the lower end of said wall having an arcuaterecess extending from one edge to the other, said wall substantiallyspanning the outlet of the carburetor.

In testimony whereof I have affixed my signature. 7
